UNITED FREDERICK H. HARRIS, OF CHICAGO, ILLINOIS.

TEMPORARY 0R LOOSE-LEAF BINDER.

Application filed October 27, 1920. Serial No. 419,926.

T 0 all whom it may concern:

Be it known that I, FREDERICK H. HARRIS. a citizen of the United States, and a resident of chicago in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Temporary or Loose-Leaf Binders; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, and to the characters of reference marked thereon, which form a part of this specification.

This invention relates to improvements in so-called temporary binders. and is adapted to receive and temporarily hold in position sheets of paper which are folded between their side edges to constitute the leavesof a book thus held in the temporary hinder, the sheets constituting twoleaves being perforated at their folds to receive detachable binding elements of the binder whereby the double leaves thus formed maybe readily removed or placed in the binder.

One of the objects of the invention is to provide a simple and economical binder for temporarily binding loose or sewed sheets folded in the form of leaves constructed to permit ready application of the folded sheets to and their removal from the binder structure.

Another object of the invention is to proto apply others thereto.

A further object of the invention. is to provide a novel holding device for such retaining rod or.wire as to normally hold the latter in place and. constructed with looking means whereby said retaining rod or wire may be endwise displaced to release-or add sheets to the binder,-the said locking means being suitably supported on the backbone of the binder cover.

The invention consims in the combination and arrangement of the elements shown in the drawings and described in the specification, and is pointed out .in the appended claims. I

In the drawings:

Figure 1 is a fragmentary perspective view of a temporary binder; in open position, embodying my invention.

Figure 2 is a section thereof on Figures 3 and 4 aresections on the respec-,

tive lines.83 and 4-4 of Figure 2.

Figure 5 is a bottom view of the holding means for the retaining rod.

As shown in the drawings 10,10 designate the covers of the binder flexibly connected to a backbone section 11, and 12, 12 designate the sheets which are intermediately folded to constitute the leaves of the book when attachedto said binder, as shown in Figures 1 and 3. The said sheets are pierced along their intermediate portions to form openings 14 to receivea retaining, rod or wire 15 which is anchored at its ends to he binder structure in a manner hereinafter described- The said retaining rod or member is offset downwardly at its ends .16 and is straight or of direct formation at its intermediate portion 17 the central and end portions being joined by the ofiset parts 18 which extend through the openings 14 of the sheets 12 that constitute the leaves of the book when confined in the binder.

19 designates an elongated plate or bar that extends: from end to end of the backbone of the cover, and as herein shown, is

partially enclosed by a sheet metal member 20, the intermediate portion of which lies over the upper sideof the plate or bar 19, and the edge members 21, 21 of which underlap but do not meet each other at the under side of the plate or bar 19.

At one end of said plate or bar 19 is located a loop or socket fitting 22 which is formed by a narrow strip of metal that transversely overlies one end of the plate or bar 19 and is spaced therefrom on the upper side of the bar, to form a socket 23 to receive one of the offset end members of the retaining rod or member 15 in such way that when said rod or member is unrestrained, it may be removed endwise from the socket 23. An upstanding flange 24 on the adjacent end of the plate or bar 19 limits the movement of the retaining rod or member in one direction.

At the other end of Said plate or bar is located another socketor loop fitting 25 which is formed of a piece ofv sheet metal that transversely overlies the adjacent end of said plate'or bar and is attached thereto in amanner to form a socket 26 to receive the other offset end 16 of the retaining rod or member 15.

is herein shown, both of the socket fittings 22 and 25 are fixed to the ends of the plate or bar 19 by means of flanges 27 which are folded down under the marginal portions of said plate or bar 19. They may be fixedly attached thereto in any suitable manner as by being driven on said plate or bar with a driving fit, or brazed or soldered thereto.

Located at the end of the bar or plate 19 adjacent to the socket fitting 25 is a locking device which is so constructed that normally a portion thereof lies across the axis of the adjacent offset portion 16 of the retaining rod or member, and is so arranged with respect to the other parts that said last mentioned portion of the looking device may be displaced endwise of the retaining rod at a. distance so that one end of the retaining rod or member 15 may be endwise shifted from the socket 23 whereupon the latter end of the retaining rod or member may be raised above and freed from its holding loop or socket 23, together with the sheets strung thereon, whereby said retaining rod or member and the sheets can, by a reverse endwise movement of the retaining rod or member, remove or detach the other offset end of the retaining rod or member from the loop or socket 26 and thus completely disconnect the retaining} rod from its locking means.

The means for thus normally holding the retaining rod or member locked in place, while permitting its detachment to 'ether with the sheets strung thereon, as nerein shown, is made as follows:

29 designates a sliding locking member that lies beneath the end of the plate or bar 19 adjacent to the loop or socket 26. It is made of sheet metal and is formed at its outer end to provide an upstanding flange 30 which lies across the adjacent offset end 16 of the retaining rod or member 15. The said locking member has sliding engagement with the structure formed by the elements 19 and 20. It is made of such width just inside of its upstanding flange 30, or the part indicated by 31, as to lie between the undenturned flanges or folds 27 of the socket member 25, without contact with the edges of said flanges, as shown in Figure 5. The inner end of said locking member is widened, as indicated at 32., to form on both sides thereof outwardly facing shoulders 33. which are adapted for contact with the inner ends of the adjacent flanges or folds 27 to limit the outward movement of the locking member as best shown in Figure 5.

l/Vhen the sliding member 31 is in its innermost position, as indicated in full lines in Figures 2 and 5, the flange 30 thereof,

and the flange 241 of the bar or plate 19, constitute means to hold the retaining rod or member 15 from endwise movement. The sliding member may be locked to the plate or bar 19 to hold it in its inner position by means of a spur 34 that is adapted to extend into a socket 35 formed in the bar or plate 19, as best indicated in Figure 2. lVhen the said locking member is pulled outwardly to the dotted line position indicated in Figure 2, the flange 80 thereof is spaced a sufficient distance from the end of the offset portion of the retaining rod or member 15, so that the latter and the sheets 12 strung thereon may be moved to ward the outwardly displaced flange 30 until the other offset end 16 of the retaining rod or member passes out of the socket '23, whereby the leaves and their retaining rod or member may be disconnected from the other parts of the binder structure.

The said plate or bar 19 with its enclosed member 20 may be and is herein shown as attached to the backbone 11 of the book by rivets 36 which thus retain said parts fixedly on the backbone of the cover.

From the foregoing description 'it will be understood that the perforated sheets when attached to the binder structure in the manner shown, constitute the leaves of a book which are folded about the retaining rod or member when the covers of the books are closed, and that a leaf or leaves may be added to or abstracted from the binder by proper manipulation of the looking device 31 before described.

It is to be understood that the invention is capable of embodiment in structures specifically differing from that herein shown and described, within the spirit of the broader claims hereto appended. For instance, the overlying sheet metal member 20 that surrounds the bar 19 affords at one end of the binder guides for locking plate or clip, but such guiding means, when the sliding locking plate is employed, may be otherwise constructed.

It will, furthermore, be understood that the upstanding flanges 30 and 24 are so spaced as to engage the side ed es of the sheets or leaves and thereby avoid a tearing stress on said sheet or leaves, at the perforations thereof, when the offset 17 of the retaining member extends through the apertures. The sheets to be thus temporarily bound in the binder may be loose individual sheets, or each retaining member or rod (if more than one be employed as shown in Figure 3) may sustain a sewed pamphlet.

I claim as my invention:
